Power LED from RF?
Can be found at http://www.creative-science.org.uk/mobile_LED_simple.html
What I would like to do is to power LED but from a distance, preferably Radio Stations of (if possible) power lines.
LED does not have to be constantly on or bright, it can "blink".
I was looking at Joule Thief and combining it with capacitor ...
The point is that there should be no battery.
Is such a thing possible?
